摘　　要：目的比较银汞材料与MTA材料作为根尖倒充填材料的不同临床疗效。方法采集既往实施根尖外科手术病例86例,按倒充填材料不同分为2组,A组47例,用MTA材料;B组39例,用银汞合金胶囊。2组均在根管显微镜下使用超声器械进行根尖倒预备。根据临床及X线片判定标准判定术后疗效,分为完全愈合、不完全愈合、不确定愈合、失败4组,统计术后1年手术成功率。结果不同的倒充填材料间成功率比较无统计学差异。结论银汞合金与MTA材料在显微超声根尖倒预备中,作为倒充填材料的临床效果无显著性差异。Objective To compare the clinic effects of amalgam with mineral trioxide aggregate as root-end filling materials during root-end surgeries. Methods A total of 86 cases that had received root apical operation were collected. According to the different root-end filling materials, these cases were divided into two groups： A （47 cases ）： MTA; B （38cases） ：amalgam; All cases were treated with microscope and ultrasonic retro-tips. The effects were evaluated by clinical and radiographic checkup. The results were evaluated as complete healing, incomplete healing, uncertain healing and failure. The operative success rate at one year was calculated.. Results The sueeess rate of group A was not significantly different with that of group B （ P 〉 0. 05 ） . Conclusion As root-end filling materials in this clinical prospective study, MTA and amalgam had the same clinical effectiveness.
